Finalize n8n Workflow

I seek an adept freelancer to finalize and optimize my automated n8n workflow, integrating RunComfy, Kling, and Grok AI with Google Sheets. The existing workflow reads configuration from a Google Sheet to determine LoRA usage, generates structured prompts via Grok AI, and processes images for further steps. Key tasks include replacing the unstable RunPod API with the reliable RunComfy API, integrating the Kling Video API for complete video processing, and ensuring all existing functionalities remain intact. I can provide the full workflow JSON file and necessary API keys for seamless collaboration.
